KW H.A.S. Nissan GT-R Skyline (R35)

KW Height Adjustable Spring Kit (HAS) — Nissan GT-R R35 (25385006)

A height-adjustable spring kit that works with the factory struts and mounts — and the reason it exists is specific to this car: it does not interfere with the factory electronic damper control.

That's the whole argument for it over a full coilover on an R35. The GT-R's adaptive damping is genuinely good, and a conventional coilover kit means giving it up. This lowers the car and adds spring rate while every driver assistance system and comfort feature of the adaptive suspension stays intact.

Height adjustable front and rear, with threaded collars on both ends. That means you're not locked into a fixed drop the way conventional lowering springs force you to be — you set the ride height after installation and can change it later when the wheel and tire package changes.

Spring rates: 800 lbs / 363 kg front, 460 lbs / 209 kg rear.

Springs are chrome-silicon steel with rates specifically developed for the OEM dampers and the GT-R's wheel loads. Composite spring seats and trapezoidal shock threads give durability, load capacity, and easy adjustment — and the design avoids the squeaks and pops that plague cheaper sleeve kits, by using correct rates and retaining the factory rubber mounts.

Fitment: 2009-2024 Nissan GT-R R35. Nismo models use a different part number (25385010).

Uses your factory struts and mounts. Nothing to remove from the electronic system, no modules, no controller.

The right choice if you want a lower, sportier R35 without spending on a full coilover setup or losing adaptive damping. If the car is track-focused and you're prepared to replace the dampers entirely, a full coilover is the other direction.
